Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the invention provides a comment method based on a blockchain, which is applied to blockchain link points in a blockchain platform, wherein the blockchain platform is used for providing, storing and distributing user comments and online content ratings. The blockchain platform is based on a blockchain technology, provides a distributed and publicly-accessed rating and rating framework, and is suitable for rating and rating movies, services (such as tourism, hotels, catering, health and the like) and entity products (such as electronic products, food, automobiles, clothes, homes and the like). The blockchain platform is a decentralized system which cannot be manipulated, an intelligent contract with reliable content is established, completely transparent product reviewers and identities are provided for users, and all parties can create values from online reviews.
The architecture of the blockchain platform is shown in fig. 1, and the blockchain platform includes a blockchain bottom layer architecture, a mechanism policy layer and an application layer. The block chain underlying architecture adopts a block chain + IPFS (inter platform File System). The public blockchain adopts a distributed storage framework of a general blockchain, and the data of the private blockchain is stored in the platform local server and the IPFS. The bottom layer technology architecture is divided into a data layer and a network layer, and a block chain, an account, a certificate, an intelligent contract and distributed storage are formed. The mechanism policy layer contains four policy blocks: credit mechanisms, incentive mechanisms, official mechanisms, and advertising. The application layer comprises various terminal products (such as platforms supporting iOS, Andriod, Web Browser, WeChat ISV and the like) provided for users, and various interfaces (API) for interacting block chain data, which are required by the users and developers, and comprises components such as log storage, service monitoring, message queue, authorization verification, unified account, data statistics and the like.
A hybrid architecture is introduced into the block chain platform, as shown in FIG. 2, a public block chain (such as an Ether house) is adopted as a main chain, and a high-performance and extensible private side chain is combined to bridge trading services, so that the interaction of the certificate of the government is realized. Key reasons for not using a pure public link architecture are scalability and transaction fees. This hybrid architecture helps to avoid network charges for transactions between users, avoid stress on the network due to large numbers of transactions, and improve the user experience in terms of responsiveness and latency.
The public block chain selects the decentralized public block chain network of the Etheng as a decentralized network layer of the block chain platform, and transparent non-falsifiable transaction and evaluation behaviors are realized by utilizing a native certificate generated by a special intelligent contract system and an ERC20 standard. The BRS (block based Review System) Core is a high-performance and expandable private block chain, and is used to record details of comments and transactions, so as to reduce transaction costs for using the ethernet network, reduce pressure on the public link network, and delay due to a large number of transactions. The transactions and behaviors of the merchant and the user on the BRS application program and other systems are stored in the BRS Core block chain, so that the comment transparency is ensured, and the fraud is prevented. Since the information is stored on the blockchain and cannot be manipulated, transparency is guaranteed. In order to facilitate individuals or companies to construct own comment systems on the platform by using BRS SDK (software development kit), a BRS comment service module is designed, and is a comment service constructed on the blockchain platform. BRS Token is the native pass-through of the blockchain platform. Based on Ether Fang, the application program runs in decentralized network environment according to established program, and completes contract content under the protection of cryptology.
The BRS bridge provides bridging services for private side chains for synchronizing payment transactions and interacting with intelligent contracts on etherhouses using BRS certificates. The certificates between the private chain platform and the Etherhouse blockchain can be dynamically interchanged. Thus, the balance of BRS on ether houses is equal to the liquidity of the certificates of currency within the private chain. The locking mechanism in the smart contract should ensure consistency of the user wallet balance between the public and private platforms.
The review method provided by the embodiment of the invention is applied to the blockchain nodes in the blockchain platform, and before the blockchain platform is used for reviewing products or services, a user firstly needs to register in the blockchain platform. The user refers to a user who searches product information and corresponding comments by using the comment service on the blockchain platform and writes own comments and scores. And the user sends a registration request to the blockchain node through a terminal such as a mobile phone or a computer of the user. The block chain node receives a registration request of a user sent by a terminal, if the registration request is confirmed to include expert authentication data, expert identity information is generated for the user after the expert authentication data is approved, the expert identity information is sent to the terminal, account information corresponding to the user is created, the account information is used for storing personal data of the user, and the expert identity information is stored in the account information of the user. The expert authentication data may include, among other things, a resume of the user, a proof of professional domain knowledge, a personal experience, and the like.
If the block link point determines that the registration request does not include the expert authentication data, generating common user identity information for the user, sending the common user identity information to the terminal, and creating account information corresponding to the user, wherein the account information is used for storing personal information of the user and storing the common user identity information in the account information of the user.
Each user has own personal data, and the user can upload information related to the interest and the preference of the user through the terminal. The general user identity information and the expert identity information are used for identifying the user level corresponding to the user, and the user level can be determined by the owner of the review service. In order to obtain the benefit of the certificate, the user needs to register a private key and an address, wherein the private key is identity information of the user, and the identity information is a digital identity and is used for providing a traceable identity for the user. But does not mean that personally identifiable information is exposed, but rather that all of the user's comment entries are signed with a unique private key whose purpose is to confirm that a particular transaction is from a particular user. Thus, the user will not be able to create duplicate reviews of the same identity, nor will someone be able to manipulate the reviews after posting. Therefore, the block chain platform distributes unique digital identity for each user, and a set of credit system is established through an intelligent contract, so that anyone can browse public records of members and judge whether the other side is reliable or not.
After the user registers in the blockchain platform, the user can evaluate the product or service by the commenting method provided by the embodiment of the invention, referring to fig. 3, wherein the method comprises the following steps:
step 101: and receiving comment information of the user on the target content, which is sent by the terminal, wherein the comment information comprises user identity information, user credit rating, a content identifier corresponding to the target content and comment description information.
When a user browses some products or services through the terminal, the content displayed to the user through the interface comprises options of rating or commenting on the content provided by the user. As shown in fig. 4, the content (110) that the interface (100) presents to the user includes: options for rating or commenting (120) on the content are provided. In FIG. 4, the interface provides the user with a function to view the article to determine if the article fits all readers (130) and fact accuracy (131), and to provide a quality rating (132). The user may click on the "submit rating" button for a comment.
After a user clicks a comment interface in the interface, a terminal sends comment information of the user on target content, and sends the comment information to a block link point, wherein the comment information comprises user identity information, user credit rating, a content identifier corresponding to the target content and comment description information. The user identity information is a digital identity generated for the user by the block chain platform when the user registers. The user credit rating is used to identify the trustworthiness of the user. The content identifier of the target content may be a content URL, a content digest, a content segment or snippet, a content hash code, a snapshot of the content creator/author/owner, etc. The comment description information is data such as scores, texts, pictures or voice clips for evaluating the target content by the user.
Step 102: and determining whether the comment information meets a preset credit rule or not through the intelligent contract.
The block chain platform creates a set of credit system through an intelligent contract, which is called as a preset credit rule in the embodiment of the application, and the preset credit rule specifies that a user with a low credit level cannot evaluate a merchant with a high credit level. After receiving the comment information sent by the terminal, the block link points acquire the credit rating corresponding to the provider of the target content according to the content identifier included in the comment information, and judge whether the user credit rating included in the comment information is greater than or equal to the credit rating corresponding to the provider through an intelligent contract. If yes, the comment information is determined to meet the preset credit rule through the intelligent contract. If not, determining that the comment information does not meet the preset credit rule, and sending prompt information for prompting that the user cannot evaluate to the terminal.
Step 103: and storing the comment information in the block chain node when the comment information is determined to meet the preset credit rule.
The comment information is stored in the block link points, so that the comment information is real and cannot be tampered. Each rating or evaluation of a user through articles, pictures, sound clips, etc. is considered as a behavior of one evaluation stored in the record of the block link points. A single tile link point may record the criticizing behavior of one or more different users. The comment behavior corresponding to each stored record comprises: information that can identify the rater/critic identity (based on the user provided rights, personal identity information is not disclosed), the rating provided by the user, details of the source of the rating content, etc. Users and organizations can acquire and analyze data from block link points. Also, the blockchain data is generated and stored under the permission of a user (e.g., a user who provides content, a user who provides comments, etc.).
For example, after the user submits the comment information through the interface shown in fig. 4, the tile link points create a tile chain record (150) according to the comment of the user, as shown in fig. 5. In the case of obtaining permission to submit the user, the tile link will store details of the user review operation (160), such as the identity (or brand name) of the user (scorer), the identifier of the content being scored, the score provided, etc. Wherein, the scorer information comprises a global scorer identifier, a scorer level (indicating whether the scorer is an authentication or verification user) when scoring, and other scorer information. The rating information is optionally encrypted and is determined based on information such as rating time, rating location, factual status of the content, security or suitability of the content or different audiences, originality of the rated content, comments, and other details. The content identifier stores information about the rated content, such as a content URL, a content digest, a content fragment or excerpt, a content hash code, a snapshot of the content creator/author/owner, and the like. In the example of fig. 5, the blockchain records contain audit records of operations on multiple users (160, 161, and 162) and are connected to other blockchain records (170, 180).
The scores or reviews submitted and saved by the user in the blockchain may be integrated into different applications. In addition to the comment options provided by the interactive interface described above, the application of social media may also provide comment options. When a user scores an article in social media, the application retrieves the user's identity identifier from the scoring platform, generates scoring time, location, content information, etc., and integrates the data with the score provided by the user and uploads the data to the platform. When a user's scorer id is missing or not present, a new scorer id can be created for the user. The review platform may also sort the records according to direct input by the user. The score/comment button allows the user to submit the score/comment directly. The platform will assemble and package the scored details to create a blockchain record.
The BRS platform may also rank the user's scores differently. The rating platform classifies ratings into categories such as authenticated user ratings, expert ratings, all user ratings, and the like. The scores may be displayed by the website/content owner and the social platform. Content providers or authors may present reviews, particularly reviews from certified/expert scorers, to enhance credibility. The user is encouraged to provide accurate ratings/comments.
The BRS platform may also aggregate ratings for each content item in conjunction with machine learning and NLP (Natural Language Processing) techniques. The user may retrieve and view the aggregated rated content. This can reduce the appearance of duplicate content and save time and effort costs for browsing the commented or scored persons.
The user can obtain a certain credit accumulation and token reward after accurately commenting the service provider each time, and the merchant can also obtain the credit accumulation when obtaining the comment and confirming. Specifically, the block link points acquire user account information of the user according to the user identity information, and increase credit points included in the user account information by a first preset score. The first preset score can be an increment of a user credit score which is preset every time of commenting, and as the number of times of commenting by the user increases, the credit score of the user is higher and higher, and the corresponding credit level of the user is also higher. The block chain node also acquires the merchant account information of the provider of the target content according to the content identifier included in the comment information, determines a second preset score according to the comment description information, and increases the credit score included in the merchant account information by the second preset score. The higher the evaluation of the comment description information on the target content is, the higher the second preset score is.
In the embodiment of the invention, if the comment information of the user on the target content causes disputes between the user and the provider or other transactions cause disputes between the user and the merchant, a settlement mechanism is adopted to settle the disputes. The BRS's equity delegation mechanism uses the idea of dPOS (Delegated Proof of merit) equity Proof mechanism to design a dispute resolution system, because dPOS is currently the fastest, most efficient, most distributed and most flexible consensus model.
When a dispute occurs, the user sends a dispute resolution request to the blockchain node through the terminal. And the block chain node receives a dispute resolution request sent by the terminal, wherein the dispute resolution request comprises user identity information, dispute description information, evidence information and the like of the user. The party initiating the official deal triggers the dispute resolution system via an intelligent contract. The originating policeman is required to pay a dispute resolution service fee. Both disputes can upload evidence to the IPFS file system, which is recorded in block link points.
And the block chain node acquires the activity degree and the credit level of the user according to the user identity information included in the dispute resolution request, and selects the public settlement member according to the activity degree, the credit level and the dispute description information. And (4) forming an ecological group by the selected public members. The dispute description information comprises the amount of money involved in the dispute, and the system automatically constructs ecological groups (at least 5) of corresponding number of people according to the amount of money involved in the dispute, wherein the ecological groups comprise more credit accumulation persons, persons with the same experience or more money holding amount. The choice of the ecological group is based on the liveness and credit score of the official sponsor.
After the members are selected out, the block chain nodes send the dispute resolution request to each member, receive the voting information returned by each member, determine the dispute resolution result according to the voting information, and send the dispute resolution result to the terminal. And finally storing the dispute resolution request, the voting information and the dispute resolution result in the block link point. The informed ecological team votes according to the evidence, and the votes are finally published in the blockchain. The ecological team will receive the corresponding BRS Token as a reward.
If any party at issue is not satisfied with the arbitration results, a complaint may be made. The dispute service fee to be complained is doubled every time, the number of people of the ecological group is doubled, and the complaint cannot be made again until the dispute service fee exceeds the reimbursement amount of the complaint. The dispute system may distribute funds to the respective disputes based on the final voting results of the last time.
In the embodiment of the invention, the user can obtain the expert identity after the expert authentication data is approved by the system by uploading the expert authentication data during registration. In addition, the expert identity can be obtained by issuing a large amount of high-quality comment information. Specifically, the block link points count the quality scores of each piece of comment information generated by the user corresponding to the general user identity information, if the number of the comment information with the quality scores larger than a preset threshold is larger than or equal to a preset expert level number, the general user identity of the user is upgraded to the expert identity, expert identity information is generated for the user, and the expert identity information is sent to the terminal. And replacing the common user identity information in the account information of the user with the expert identity information.
And for all users with expert identities, the system also acquires all comment information generated by the users in the preset unit time length at intervals of preset unit time length according to the expert identity information, determines the number of the comment information of which the quality score is greater than a preset threshold value in all the comment information, cancels the expert identities of the users if the number of the comment information of which the quality score is greater than the preset threshold value in a certain continuous preset unit time length is less than the preset number, generates the identity information of the common users for the users, and sends the identity information of the common users to the terminal. And replacing the expert identity information in the account information of the user with the common user identity information. Wherein, the quality score of the comment information is determined based on the number of the users' likes or agrees and other factors. The preset unit time may be one week or one month, etc.
In the embodiment of the present invention, the participants of the system can be divided into four categories, which are: general users, merchants, review experts and advertisers:
1. business company
Merchants are parties that offer products or services that require feedback from people on the products or services to improve their quality and competitiveness in the marketplace. To join a BRS system, a merchant must physically register with the BRS, including its business scenario, scope, product service details, etc., and may need to pay for the registration or product listing fee.
2. Expert
An expert refers to a user who qualifies and will review the products and services of the system. The expert's comments may be displayed separately when reviewing a product or service. There are two ways to become experts:
(1) and registering in the BRS. And uploading expert authentication data such as resume, professional field knowledge proof, personal experience and the like to the platform for auditing. The applicant can only have the expert identity after approval. This class of experts must submit a certain number of high quality comments each month (based on factors such as the number of users' likes/agrees), and will be demoted to the average user if the experts fail to meet these conditions for a continuous preset number of unit durations.
(2) Publishing a large number of widely accepted (liked/agreed) high quality reviews. After reaching the designated level, the commenter promotes to be an expert. Note that depending on the scale of development of the system, this threshold may also be increased accordingly.
3. General users
Ordinary users refer to those consumers who use the BRS. The point-evaluating system can search products and point-evaluating information and can edit evaluation and scoring of the point-evaluating system. The general user can become an expert in the above-described manner. The ordinary user will also receive the BRS voucher as an award based on the system settings and their review records.
4. Advertising businessman
An advertiser refers to a business or individual who wants to advertise on the BRS platform. Of course, the merchant may be an advertiser, with the independent advertiser being treated as a special category of merchant on the BRS. Advertising revenue will be distributed to system participants according to the configuration of each system on the BRS platform.
The BRS platform builds a credit system through the decentralization, traceability and information inflexibility of the block chain, and provides trust and safety-based user experience for ecological participants. The BRS builds a credit system through the public distributed account book of the Ether house. This system lets all participants in the ecosystem accumulate credit points through good behavior. Anyone can browse the public records of the members and judge whether the other side is reliable. Based on a complete credit mechanism, a new incentive policy is put forward for community high contributors with higher credit, higher grade, more held coins and the like. As the degree of contribution increases, the token prize won after each contribution also varies, with higher contributions yielding more prizes. The consumer receives the token award through a real comment, and the token award received varies with higher credit rating. And the system can also automatically release service and share invitation members to join in obtaining token rewards. In addition, a low credit facilitator may offer more tokens in the service to attract users.
The current criticizing ecology does not bring qualitative changes to the market, the BRS reconstructs an incentive mechanism, adjusts and optimizes the value distribution of the market through BRS Token, and continuously incentivizes participants in the criticizing ecology community. At the same time, the more the user contributes, the more kinetic energy the incentive adds to the user. Behavioral incentives for the service partner: s (service)×Number of good comments×Credit rating) token. Behavioral incentives for consumers: c (amount of consumption)×Comments×Number of praise×Credit rating) token. The sharing behavior of the user is stimulated: sharing×The number of people is token.
In the embodiment of the invention, the Token is injected into the excitation pool according to a certain increment every year except that the Token used in the release is finally injected into the excitation pool. The incentive pool distributes the bonus and rewards according to the priority, and the reward types are divided into behavior reward and coin-in reward. The incentive pool can settle the wallet address which accords with the behavior incentive in real time through the intelligent contract, and periodically settle the reward of holding coins. 60% of the incentive pool is used as behavior incentive, and 40% is used as coin-holding incentive.
The specific process of releasing the advertisement and rating activities on the BRS platform comprises the following steps: 1. the merchant first provides the ad placement details (links, conversion targets, …) and then creates a new product review request, or a new ad campaign bid, on the BRS; 2. the merchant has deposited a certain number of BRS passes (say 1000BRS Token) into the intelligent contract. The BRS of the pledge is locked when the permit is passed, and the bid is waited for approval; 3. the staff reviews and approves the bid, and if the bid is rejected, the deposit is returned to the merchant; 4. upon approval of the bid, the BRS review service will be notified to execute the bid; 5. bidding is performed according to the bidding parameters. 6. This operation will be recorded on the BRS Core private block chain whenever the user clicks on the advertisement link; 7. when a user clicks and submits comments, the evaluation details are recorded on a BRS Core private block chain, and the comments are required to be approved by BRS workers or required to be approved by expert users; 8. once bids are executed or due, BRS intelligent contracts are invoked along with statistical information to allocate the cost and revenue share of the user and BRS passport holder.
Note that the bidding state on the public chain will be synchronized to the BRS Core private block chain through the BRS bridge.
